Over the course of the past decade, NASA spacecraft have identified several sites on Mars where conditions capable of supporting life existed in the past. One of the most promising of these sites, and a good candidate for a follow-up mission designed explicitly to look for signs of life, is the shallow subsurface at the Phoenix landing site in the arctic northern plains of Mars. Indeed, the region where Phoenix landed some scientists believe, may still be habitable today. As an early step toward developing the technology for a return mission to the martian polar north, members of NASA's IceBite team will head out this month to explore University Valley, in Antarctica's Dry Valleys. Astrobiology Magazine will be following their activity while they're in the field, regularly posting blog entries from IceBite team member Margarita Marinova. Visitors to the Astrobiology Magazine site will be able to ask questions of the IceBite team by clicking the Ask a Scientist button that will appear in our IceBite stories and blog entries. Read more
NASA's IceBite project will spend three austral summers in Antarctica testing ice-penetrating drills for a future mission to Mars. A team of seven scientists recently returned from the first field season, installing scientific probes in the ice and frozen ground, and scouting for sites where the drills will be tested the following year. One of the team members, Margarita Marinova, wrote a blog of the team's activities. In this third set of entries, she describes the team's return from Lake Joyce to McMurdo Station, and work at a second field site, University Valley. Read more
